Aiming at the abnormal strata behavior in the advance entry of 1303 fully - mechanized working face in xinglongzhuang coal mine, the movement rule, characteristic, step distance of fracturing, position and mode of fracturing of the overlying strata in mining process is analyzed by using the key strata theory
摘要針對興隆莊煤礦采區1303綜放工作面超前平巷發生奇異壓力的現象，採用關鍵層理論對在采動過程中的上覆巖層運動規律進行了詳細的力學分析，研究了它們的運動特徵、破斷步距、斷裂位置、斷裂方式以及對工作面及其超前平巷的來壓規律，對比分析了該工作面礦壓實測數據與理論研究成果。On the basic of former research men ' s experience, 18 experimental members ( including 9 simple beams and 9 restrained beams ) are designed and tested. in the experiment, phenomena are observed and record by taking photos in the whole process from the first crack appears to test members crash completely, experimental data is attained including load values of crack - appear load, critical load and terminal load, stress values of reinforcing steel bar stress, compressed concrete stress and beam flank stress and values of deflection etc. by analyzing the crack ' s appearing and developing form and stress values of concrete and steel bars, the crash modes of test beams are defined ; shearing force - deflection curves are contrasted and analyzed ; the effects on shear strength of the three factors as shear span ratio, concrete strength and restraining moment are also analyzed
借鑒已有試驗的經驗，本文設計和完成了對18根超高強混凝土無腹筋梁（包括9根簡支梁和9根約束梁）在集中荷載下抗剪強度的試驗，觀察了試件從裂縫出現到完全破壞失去承載能力全過程的試驗現象並通過拍照進行記錄，獲得了試件的斜裂縫出現荷載、臨界斜裂縫荷載和極限荷載等荷載值和縱筋應變、混凝土受壓應變和梁側混凝土應變等應變值以及撓度值等。Viewing solely from their performance, mdf, dsp, rpc all enjoy a high compressive strength. their flexural strength, fracture toughness and elastic module have broken the limit of traditional cement based materials. all these materials have acquired the features of high toughness material
從材料性能審視，無宏觀缺陷水泥基材料、均布超細顆粒緻密體系、活性粉末混凝土等的抗壓強度都非常之高，其抗拉強度、斷裂韌性和彈性模量也突破了傳統水泥基材料的限度，這些材料具備了高強韌性材料的特徵。
